To all whom t may concern;

Be it known that I, VVALTER F. RormR, a citizen of the United States, and a resident of Hopedale, county of VVor-cester, State of Massachusetts, have invented an Improvement in Shuttle-'Checking Means for Looms, of which the following description, in connection with the accompanying drawings, is a specification,

like characters on the drawings representing like parts.

This invention hasfor its object the production of novel means for checking the'move-l ment of a loom-shuttle when boxed, whereby a greatly-increased surface friction is attained, with consequent efficiency. in vthe action.

rlhe ordinary binder is made asa bar or arm of wood or metal or a combination thereof fulcrumed at the outer end of the shuttlebo'x and having its contact-face variously shaped to act upon the incoming' shuttle.

lA binder-springmaintains the binder in position to be struck by the incoming shuttle, and the force of the blow swings the binder outward,while the shuttle continues its movement in the box, and the shuttle may sometimes continue almost to the end of its stroke before being again engaged by the binder as it is moved inward by the binder-spring.v At all events the binding or checking action is practically confined to the shoulder of the shuttle during the greater part of the boxing,

it being Vmanifest that in consequence only a very limited amo unt vof surface of both shuttle and binder can exert any checking action.

Various constructions havebeen devised having in View the better and more effective checking of the shuttle, and some'of the devices have met with a fair degree of success.

In my present invention I have radically departed from the usual form ofV rigid inflexi-V ble binder and have devised a novel form of flexible binder whichis so constructed and arranged that it conforms to theshape of the shuttle as it enters and moves along in the shuttle-box, so that the checking pressure isl exerted over quite a large surface.

y checking By the use o f such a iiexible binder as will be hereinafter described I lam enabled to greatly augment the effectiveness of the checking action without the aid of strong controlling-springs, and I can also cause the inner end of the binder to remain in engagement with the shuttle from the instant of impact.

The various novel features of my invention as embodied in one practical form thereof will be fully described inthe subjoinedspecifica- `section onthe line 3 3Fig. l, looking toward Vthe right; and Fig. 4L is a front elevation of the binder detached.

In Figs. l and 2 the cover plate of the shuttle-box isbroken out to more clearly show the binder.

VThe lay A, picker-stick I), protector rock.`

shaft H, its vcontrolling-spring HX, the upturned binder-finger LX, having an adjustable contact-stud t, the dagger H2, back and front walls and cover-plate bzof the shuttle-box 'may be and are vfall of well-known or usual construction, theback wall of the box having a rearwardly-projecting shelf 6X to sustainthe inner end/of the'binder.

In accordance with my present invention the binder as a whole is made flexible in the v direction of its length by a species of articulation orjointing-in order .that it may conform outermost member c being fulcrumed at the outer end of the shuttle-box on the usual stud b3. The innermost member of the series has aprolongation c, which rests upon the projection LX and extends back of the boxwall 7), the latter limiting inward movement of the binder when the shuttle-box is empty in usual manner. I have provided a common support, connection, and controller for the said binder members, the same consisting of a thin, flat, and elongated strip cx of elastic and flexible metal, such as a leaf-spring. This support is extended longitudinally of the series of binder members, the latter being longitudinally notched or grooved, as will be explained, to receive and straddle the support, and referring to Fig. 4 I have shown the endmost members secured to the support by fastenings 2, which may be screws, rivets,or other suitable means, the grooves l in said members being just wide enough to snugly receive the support. The binder members are thus articulated or jointed by or through the coperation therewith of the support 0X. The outermost member c has an upright hole 3, Fig. 4, to receive the fulcrum stud b3, the members 0 and cr serving to prevent longitudinal displacement of the intermediate binder members on the support 0X.

Referring to Fig. l, it will be seen that normally the contact-faces of the binder members present a convex surface for thevbinder as a whole, the face of the member c presenting a shoulder or swell 4 to receive the initial impact of the incoming shuttle. Then the box is empty, the contact-face of the binder projects into the path of the shuttle, as is the case with an ordinary rigid binder. The adjacent sides of the different members are convexed from front to rear, as shown at 5, and the grooves 6 in the intermediate binder members c to ci are made with their side walls flared at the ends, as shown by dotted lines, Figs. l and 2, so that each member may rock or turn on the support to accommodate itself to the portion of the shuttle-wall opposite thereto when the shuttle enters the box. This individual rocking or turning feature of the binder members, together with the flexibility and resilience of the support and connection 0X, enables the binder as a whole to bend or flex, and thereby conform to the shape of the shuttle, and by reference to Fig. 2 it will be seen that the contact-surface of the binder has as a whole changed from convex, as when the shuttle-box is empty, to a concave form beyond the member c5 when the shuttle is boxed. As the shuttle enters the box it strikes the swell 4 of said member c5, and the binder as a whole is swung outward on the fulcrum b3, the dagger being thereby lifted sufciently to clear the usual frog (not shown) as the lay beats up. This outward swing is limited, however, by the dagger-stop H3, Fig. 3, which is adjustably mounted on the lay and adapted to be engaged by the dagger when the protectorshaft H is rocked. In practice this daggerstop is so set or adjusted that the binder member e5 can only move outward when struck by the shuttle far enough to permit the passage thereby of the shoulder of the shuttle, said member remaining in contact with and pressing upon the shuttle during boxing thereof, and thereby adding to the checking action of the binder. The resiliency of the support X permits one after another of the members e" c3, Sac., to successively engage the shuttle as it continues its movement in the box, and said members by reason of their flared grooves and convex sides 5 position themselves individually to conform to the particular portion of the shuttle opposite thereto. ',lhus when the shuttle is completely boxed the binder members will have arranged themselves to conform substantially to the shape of the shuttle, as shown in Fig. 2, and by reference thereto it will be seen that all of the binder members except the outermost one c are in engagement with and pressing upon the shuttle. The binding pressure therefore is exerted upon a comparatively large surface ol` the shuttle instead of being practically localized near or upon the shoulder of the shuttle.

So far as my invention is concerned or the operation thereof the support may be substantially straight when the shuttle-box is empty, the said support then assuming a concave shape toward the shuttle when the latter is boxed, or said support may be somewhat convexed when the box is empty, becoming more nearly straight when the shuttle is boxed.

The binder members may be faced with leather, if desired, in the manner that ordinary binders are sometimes made.

My invention is not restricted to the precise construction and arrangement herein shown and described, as the same may be modified or rearranged in various particulars by those skilled in the art without departing from the spirit and scope of the invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
